Coral Reefs and Land Based Sources of Pollution: The Need for Interagency and Local Collaborations

In this talk…

1. Unique conditions 2. Diverse stressors = diverse partnerships 3. Local knowledge and coordination

Loss of Historic Wetlands/Forest

Sediment

Short Watersheds

Solutions are local and have to be sustained

Common Stressors: Sediment from Bare soils

Source: Agricultural Clearing

•“quantitative linkage between terrestrially-sourced dissolved inorganic nitrogen (DIN) loading and the upper thermal bleaching thresholds of inshore reefs”

• “concrete evidence for the belief that improved watershed management/nitrogen reduction will increase the survival prospects of coral reefs to global climate change”

LBS is an actionable approach to minimize climate change impacts to coral
